l valve known as Boyles waste-overflow.7

Be it known that I, PATRICK HARVEY, a Fig. 3 shows my invention in connection with citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Auxiliary Overflows for Lavatories, of which the following is a description.

My invention is designed to prevent damage 10 resulting from the overflow of sinks, lavatories, bath-tubs, rbc., caused by stoppage of the ordinary waste-drain or overflow-waste passage, while the supply-faucets, through neglect or leakage, continue to run. Vhen such stop- 1 5 page occurs at the wasteorifice, or in the waste- 2O junction therewith of the ordinary overflowpipe, manifestly the latter can give no relief. Such stoppage is most frequent at the traps, which arenecessarily beyond the junction of the overflow with the waste-pipe,and at angles or exposed portions of the pipe still further from the bowl. This clogging, when caused by the accumulation of solid matter, particularly greasy matter, is usually gradual, and occurs, therefore, in the ordinary waste- A pipe which, on the contrary, should come only occasionally into use as an emergency-pipe would rarely become clogged during its temporary use in such emergency. This consideration leads to my invention, which consists in providing an overflow-escape independent from and without connection with the ordinary waste-pipe, leading from a point higher than the connections with the waste-pipe, and which may be from the surface of the slab or table in which the other convenient discharge-point before it rises sufficiently to overflow the entire slab and escape to the floor.

Figure l represents a usual form of lavatory with accompanying faucets and waste-escapes,

5o' and with my auxiliary overflow attached. Fig.

2 is a vertical sectional view showing my invention as connected with a form of wastea bath-tub. Fig. 4 is a detail view of the f1tting which I employ in and as part of my invention.

A is the bowl, basin, or tub. Bis the supply-faucet. C is the ordinary wasteconnec tion. D is the ordinary overiiow. E is the table or slab in which the bowl is set. F is my auxiliary safety overflow-conduit, of which F is the upper section, having the flanged or iiaring endf slinken through the slab E at the lowest point of the cavity G, from which the trough G leads to the edge of the slab overhanging the bowl. Grl is a groove or trough in the slab surrounding the bowl and draining the entire surface into the cavity G. .I is a strainer covering the mouth of the conduit F. At the center of it is fixed the ordinary chain stay, K, for the waste-stopper, thereby obviating the necessity for a separate chain stay.

The cavity G and overiiow-conduit opening therefrom may be at any convenient part of the slab; but if the slab is at all inclined it should be at the lowest point of the slab, so that the entire surface may be drained into it. When applied to a bowl or sink set in atable or slab, I prefer to make a fitting substantially in the form shown in Fig. 4, wherein the nut K is designed to be clamped below the slab,

and thereby to draw the flaring shoulder f down onto suitable packing linterposed between it and the upper surface of the slab. Vhen applied to batlrtubs set in wooden slabs,

I prefer to connect the auxiliary overflow F with the tub directly, as well as with the surface of the slab, and I have shown such connection in Fig. 3, the duct F2 being such direct connection with the tub. Vhen applied in connection with the Boyle overliowwaste, as shown in Fig. 2, my invention takes the form therein shown, the upper end of Boyles fitting being made so as to be sunken in the slab, and the cover or cap becoming the strainer J. My auxiliary overflow must then be connected into the ordinary overflow,D, ata pointhigher than that at which the water will lift the float and. open the* ordinary waste. It is so shown in Fig. 2, opening at d above the overflow-port d, and leading by ah independent course to the sewer or safety-basin.

I do not limit myself to the use of the fitting ICO described in Fig. 3, which is only a convenient I and preferred forni.

I claim- 1. In a lavatory, bath-tub, or sink, the coinbination of a basin, a waste-pipe, and an in- 7 dependent auxiliary overflow escape-conduit connecting with the upper part of the basin, but not With the Waste-pipe, so as to relieve the basin when the Waste-pipe and ordinary overflow are closed.

2. In a lavatory, bath-tub, or sink, the conibination of a basin, a Waste-pipe, a containingslab having,` the groove in its upper surface, and an independent auxiliary overilow escapeconduit connected with the groove in the surface of the slab, but not with the waste-pipe, substantially as described and shown.

'3. In combination with the slab'of a Washbasin or sink, having a cavity, G, communicating by a groove or spout, G, with the Washbowl, a conduit leading from such cavity apart from the ordinary Waste-pipe, provided With a strainer, J, over the mouth of such conduit, and a chain stay secured to such strainer, substantially as set forth.

l Intestimony whereof I have hereunto set my hand, in the presence of two Witnesses, at Chicago, county of Cook, and State of Illinois, this 9th day of August, A. I). 1883.
